Be it known that I, HENRY A. WVIsn 001), a citizen of the United States; residing at New York, in the county of New ,York and State of New York; have invented a new and useful Paper-Pin Holding and Adjusting Device, of which the following is a specification.

This-invention relates to the rotary. folding cylinders of web printing presses and the principal objects thereof are to provide a paper forwarding pin without screwthreads, and yet having means whereby it can be removed and replaced easily and at small cost, and to provide simple and accessible means for adjusting each individual whereby the operator can regrind. old pins that may been damaged or slightly broken at the point, thus reducing The holding device is so arranged that the head of the pin, independently of its length, is always held firmly against a seatas desired without affecting the of parts as will appear ing drawings,-

'well known form of sisting of a cutting cylinder vided with a ing surface and the adjustment is arranged so that each individual pin can be adjusted simultaneous operation of all the pins by the usual pin rod. v

The invention also involves imp-'ovements vindetails of constructionand combinations her'einaften' to be had to the accompanyin which'- 7 1 1 is a' "transverse sectional 'viewof Reference is Figure a portion with a preferred embodiment of tion applied to the former; Fig. 2 is a detail side vieW,-partly in section, of the'pin adjusting-mechanism; Fig. 3 is an elevation of one of thepin adjusting segments showing the adjusting and fastening screws re: "moved a slight distance therefrom; Fig. 4 is an enlarged central sectional View of a pin-holding device; and l ig. 5 is an end view of the same.

The invention is folding couple con- 10 and ing. cylinder 11. Asusual, the cylinders have pin rods or shafts dinally thereof and oscillatably supported on the cylinder. This rod is shown as pro- .plurality of a series 0 teeth 13 therearound so that it constitutes a plu- Arias FATE N. Y., ASSIGNOR,' BY MES NE CORPORATION; OF NEW YORK,

to micrometrically adjust each pin ndependently.

As is usually thecase, mounted ina passage in the cylinder so as to be-moved longitudinally. It is provided with a rack 21 fitting the teeth of the seg-- mental gear 14 for this purpose.- t is obviou's that when the'gear is adjusted back and forth the pin holder also will be adjusted. In the end of this holder' 20 is a central longitudinal socket 22 which is provided with. screw threads and has a conical. seat 23 at the'bottom. i

This seat is for receiving the head 24 of the This pin is smooth instead of screw ed,as usu 1. .It extends out centrally beyond the end of the socket. For the purpose of holding this pin firmly and simply a nut '26, is provided having a head 27 at the longitudinal smoothv perforation for receiving the pin. en it is desired to remove the pin the nut is unscrewed from the socket, the pinreplaced by another, and

-It will be seen from the description given ifords an exceedingly of. clamping api'ri -inde enderitly of I its ividually so that the operation of the pin rod will cause all thepins to operate accurately whatever their lengths. At the same time,

This, clearly, therefore is a material econom over the usual constructron which requires the threading of each pm. I

Although I have illustratedand described only single embodiment of the invention and shown only a single application there fact that many modithe scope of the invention as expressed in the claims. Therefore, I do notwish to be limited in these respects, but

WVhat I do claim is 1. In a paper folding device, the combinatlon with the cylinder, of a pm operating device carried thereby, means connected with said device for simultaneously operating a plurality of paper holding pins, and means connected with said device for individually adjusting each pin with respect to the device, saiddevice being provided with means at intervals for cooperating with said adj usting means.

' In a paper folding device, the combination with the cylinder, of an oscillatable pin operating rod carried thereby, a plurality of means connected with said rod for simultaneously operating a plurality of paper holding pins; means connected with said rod for individually adjusting each pin micrometrically .with respectto the rod, and independent means for clamping the operating evices in adjusted positions on the rod.

3. Ina paper folding device, the combination with the cylinder, of a pin operating rod carried: thereby, a plurality of means connected with said rod for simultaneously operating a plurality of paper holding pins, a series of teeth on the rod at separated points, and a worm connected with each pin operating device for engaging said teeth and moving individually with respect to the rod..

4. The-combination with a cylinder, of a longitudinal rod thereon having a series of circumferential teeth, member rotatably mounted on the rod, means supported by said member and engaging said teeth for adjusting said member about the rod, means for clamping the member to the rodin it's positions, a movable pin holder,

It is the pins that break having a passage therethrough,

each pin operating device, fi

about the rod, means for clamping the gears to the rod in their adjusted positions, and a longitudinally reciprocable pin holder having arack thereon for engaging the teeth of one 'of said segmental gears, whereby said holder can be reciprocated and adjusted.

6. In a paper folding device, the combination with a cylinder, of a holder thereon, means for reciprocating the holder longitudinally, said holder having a socket in the end thereof for the end of a paper holding pin, and readily removable means entering said socket for holding the'head of said pin in a definite position therein against said socket.

7. In a device of the character described, the combination with a holder having a screw-threaded axial socket in the end, and a nut fitting said serew-threaded socket and of a .smooth,

headed pin extendin through said passage, s anarticle 0 l112l.nllfa(}l l11', a holder fora paper pin havinga screw-threaded socket, anda nut having'a passage therethrough for the pin and adapted to be screwed. into said socket to hold the head of the pin therein.

9. 1 As anarticle of manufacture, a holder for a paper pin having a screw threaded socket in the end thereof and provided with a seat at the bottom of said socket, a smooth pin having a head fitting said seat and adapted to project from the seat through the socket,-.and :1 threads against said seat.

In testimony whereofI have hereunto set my hand, in the presence of two Subscribing witnesses.
